Error correction models are widely used to estimate dynamic cointegrated systems. In most applications error correction models are reduced form models. As a result, non-structural speed of adjustment coefficients are estimated in these applications. A single equation instrumental variable method...

This paper develops a system instrumental variable method to estimate the speed of adjustment coefficient in the long-run equilibrium of structural error correction models for a class of linear rational expectations models. This method is applied to an exchange rate model with sticky prices, in...

When univariate methods are applied to real exchange rates, point estimates of autoregressive coefficients typically imply very slow rates of mean reversion. Rogoff (1996) discusses that the remarkable consensus of 3-5 year half-lives of purchasing power parity (PPP) deviations is found among...

When univariate methods are applied to real exchange rates, point estimates of autoregressive (AR) coefficients typically imply very slow rates of mean reversion. However, a recent study by Murray and Papell (2002) calculates confidence intervals for estimates of half-lives for long-horizon and...

The paper examines the convergence question by contrasting the half-lives of deviations from purchasing power parity (PPP) across traded and nontraded goods in an exchange rate model with sticky prices. In particular, empirical results show that in most cases the half-lives of PPP deviations for...

The goal of this paper is to examine the hypothesis of real interest rate parity by contrasting real interest rates across traded and nontraded goods under flexible exchange rates. We employ panel unit root tests to investigate the stationarity of real interest rate differentials. In particular,...

This article examines whether Inflation Targeting (IT) matters for long-run Purchasing Power Parity (PPP). For this purpose, we formally assess the evidence on PPP for a panel of 19 countries using two price indices and two panel unit root tests with cross-sectional dependence. The empirical...
